It appears that you have never been a "prophet-in-training."
Perhaps we can have a more meaningful dialogue if you return after 10-20 years of being a "prophet-in-training."
It appears that we will escape a quake in Oregon and Wash etc. Praise God for that.
I have no idea if prayers have changed things or if the fellow heard wrong or what. I don't really have an answer. He does NOT come across as a false prophet at all.
It's not the way I think that I'd run things.
But God knows infinitely better than I.
Personally, I'd like to see Him do some demonstration like was in THE DAY THE EARTH STOOD STILL.
But He clearly has other plans.
One thing repeated warnings may do is filter out those who truly TRUST HIM REGARDLESS.
Anyway--enjoy your perspective, if you wish. It's not mine. I'd encourage a different one but a different one does not seem likely to be in your repretoire.
Repeated false warnings are nothing more than lies, and result in faithlesness. The "prophet-in-training" theory is not scriptural, and merely false prophets to continue their foothold in the church. When God speaks to someone, it doesn't take 15 to 20 years for the prophet to 'get it right'. If the quake doesn't happen, then this man is a false prophet. The scriptures are very clear in warning us about false prophets.
